Web6 jul. 2024 · A shunt (or shunt resistor) is a device that creates a low resistance path for an electric current, to allow it to pass through another point in the circuit. Shunts are also referred to as current shunt resistors, ammeter shunts, current shunts, or DC shunts. … WebA shunt is calculated using Ohm's law, but because it's a series resistance it dissipates power. For example, if one uses a 'standard' 200mV digital display to measure up to 2A, there will be up to 200mV across the shunt. It will dissipate 400mW at maximum current (and the powered circuit gets 200mV less than the applied voltage).
